Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomizers, in particular to an atomizing core module and an electronic atomizer. BACKGROUND

[0002] At present, the atomizing core modules used in the electronic atomizers on the market have types such as cotton cores, porous ceramic cores and magnetic induction heating cores, wherein the cotton cores are further divided into types such as heating nets and spring cores according to the shapes of heating elements. At present, the heating nets on the market are mainly made of metal materials, and the shapes of such heating nets are often two metal wires directly welded at both ends for being used as positive and negative connection lines and connected with a power supply. However, the welding positions of the positive and negative metal lines have the risk of heavy metal precipitation in the process of high-temperature work of the heating element. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present application is to provide an atomizing core module and an electronic atomizer, which can solve the problem of the risk of heavy metal precipitation in the welding position of the heating element and the metal electrode in the process of high-temperature work of the heating element by changing the connection form between the heating element and the electrode element.

[0004] The embodiments of the present application are implemented as follows:

[0005] In a first aspect, the present application provides an atomizing core module, which comprises a heating element, an insulating fixing element and two electrode elements. The heating element comprises an arc surface constraint section and two plane constraint sections extending outward from both sides of the arc surface constraint section. The two electrode elements each comprise a fixed section and a pin section connected with each other. The insulating fixing element is clamped between the two fixed sections, and the two plane constraint sections are clamped outside the two fixed sections. The atomizing core module can solve the problem of the risk of heavy metal precipitation in the welding position of the heating element and the metal electrode in the process of high-temperature work of the heating element by changing the connection form between the heating element and the electrode element.

[0006] As an implementable manner, the two plane constraint sections are parallel to each other, and the distance between the two plane constraint sections is equal to the sum of the thicknesses of the insulating fixing element and the two fixed sections. The two fixed sections are parallel to each other, and each of the two fixed sections has a flat plate structure.

[0007] As an implementable manner, the atomizing core module further comprises two insulating protective sleeves, and each of the two insulating protective sleeves is sleeved on one of the pin sections.

[0008] As an implementable manner, the insulating fixing element is provided with a first matching part, the fixed section is provided with a second matching part, and the first matching part and the second matching part are matched with each other to fixedly connect the insulating fixing element and the electrode element.

[0009] In one possible implementation, the first mating part is a protrusion, and the second mating part is a groove or through hole adapted to the protrusion; or, the first mating part is a groove, and the second mating part is a protrusion adapted to the groove.

[0010] As one possible implementation, it also includes a liquid guiding component, which includes an arc-shaped covering section and planar covering sections extending outward from both sides of the arc-shaped covering section. The arc-shaped covering section is attached to the outer wall of the arc-shaped constraint section, and the two planar covering sections are attached to the outer walls of the two planar constraint sections in a one-to-one correspondence, so that the heating element, the insulating fixing element, the two electrode elements and the liquid guiding component form an atomizing assembly.

[0011] As one possible implementation, it also includes a cylindrical mounting bracket with a notch on its peripheral wall. The atomizing component is inserted into the mounting bracket axially, and the planar covering section passes through the notch and protrudes outside the mounting bracket, while the pin section passes through the opening of the cylindrical structure and protrudes outside the mounting bracket.

[0012] As one possible implementation, the mounting bracket is provided with a plurality of liquid inlet holes arranged circumferentially.

[0013] As one possible implementation, the heating element is a heating mesh or heating sheet with a mesh structure, and the shape of the mesh is prismatic, circular, square, honeycomb, or irregular.

[0014] A second aspect of this application provides an electronic atomizer, including a power module and the aforementioned atomizing core module, wherein the output terminal of the power module is electrically connected to the pin segments of the two electrode components. This atomizing core module, by changing the connection method between the heating element and the electrode components, can solve the problem in the prior art where the welding position between the heating element and the metal electrode poses a risk of heavy metal precipitation during the high-temperature operation of the heating element.

[0015] The beneficial effects of the embodiments of this application include:

[0016] The atomizing core module includes a heating element, an insulating fixing component, and two electrode components. The heating element includes an arc-shaped constraint section and planar constraint sections extending outward from both sides of the arc-shaped constraint section. Each electrode component includes a fixed section and a lead section that are interconnected. The insulating fixing component is clamped between the two fixed sections, and the two planar constraint sections are clamped outside the two fixed sections. In the actual assembly process, the insulating fixing component is first clamped between the fixed sections of the two electrode components to prevent short circuits between them. Then, the two planar constraint sections of the heating element are clamped outside the fixed sections of the two electrode components, thus assembling the heating element, the two electrode components, and the insulating fixing component. After assembly, the heating element, the two electrode components, and the insulating fixing component together form a sandwich structure. Compared to the prior art where the heating element is welded to the metal electrode, the assembly method provided in this application uses the clamping force provided by the two planar constraint sections of the heating element to clamp the two electrode components and the insulating fixing component. Since the welding step is eliminated, solder precipitation in a high-temperature environment can be avoided. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] Most e-cigarettes use metal heating elements, which typically require two metal leads soldered to their ends to connect to the positive and negative terminals of the battery, forming a circuit. Currently, the metal leads and the heating element are fixed together by soldering. The soldering material used is usually an alloy solder containing tin and lead, which melts at high temperatures, typically exceeding 1000 degrees Celsius, thus physically connecting the metal leads and the heating element. However, the soldered heating element continues to generate heat during operation, reaching temperatures of 200 to 400 degrees Celsius. While this temperature doesn't melt the solder, maintaining a high temperature environment for an extended period can cause certain alloying elements in the solder to tend to separate from the crystals, forming particles or undergoing phase separation, resulting in metal precipitation. This can affect the lifespan of the heating element and ultimately impact the flavor of the e-cigarette.

[0033] Please refer to the reference. Figures 1 to 6 This application provides an atomizing core module 100, including a heating element 10, an insulating fixing member 20, and two electrode members 30. The heating element 10 includes an arc-shaped constraint section 11 and planar constraint sections 12 extending outward from both sides of the arc-shaped constraint section 11. Each of the two electrode members 30 includes a fixed section 31 and a lead section 32 connected to each other. The insulating fixing member 20 is clamped between the two fixed sections 31, and the two planar constraint sections 12 are clamped outside the two fixed sections 31. By changing the connection form between the heating element 10 and the electrode members 30, this atomizing core module 100 can solve the problem of heavy metal precipitation risk at the welding position between the heating element and the metal electrode in the prior art during the high-temperature operation of the heating element. The heating element 10 can be a heating mesh or heating plate with a mesh structure. The shape of the mesh can be prismatic, circular, square, honeycomb, or irregular. Irregular shapes can be other pore structures with regular or irregular shapes. When the heating element 10 is a heating mesh, such as a mesh, the area of ​​the hollow part of its mesh is greater than the area of ​​the heated metal part. When the heating element 10 is a heating plate, the area of ​​the hollow part of its mesh is less than the area of ​​the heated metal part. The specific choice can be made according to the heating requirements.

[0034] It should be noted that, as Figures 1 to 4As shown, the atomizing core module 100 includes a heating element 10, an insulating fixing element 20, and two electrode elements 30. The heating element 10 includes an arc-shaped constraint section 11 and two planar constraint sections 12, and the two planar constraint sections 12 extend outward along both sides of the arc-shaped constraint section 11 (i.e., the side away from the center of the arc-shaped constraint section 11). The two electrode elements 30 have opposite polarities so that the atomizing core module 100 can be smoothly connected to the circuit through the two electrode elements 30. Both electrode elements 30 include a fixing section 31 and a lead section 32 that are connected to each other. In the actual manufacturing process, the fixing section 31 and the lead section 32 can be made by an integral molding process, which can improve the integrity of the electrode elements 30 and simplify the assembly steps of the atomizing core module 100.

[0035] In the actual assembly process, such as Figure 5 and Figure 6 As shown, the insulating fastener 20 is first clamped between the fixing sections 31 of the two electrode components 30 to prevent short circuits between the two electrode components 30. Then, the two planar constraint sections 12 of the heating element 10 are clamped outside the fixing sections 31 of the two electrode components 30 (i.e., on the side away from the insulating fastener 20). This allows the heating element 10, the two electrode components 30, and the insulating fastener 20 to be assembled. After assembly, the heating element 10, the two electrode components 30, and the insulating fastener 20 together form a sandwich structure. Compared to the prior art where the heating element is welded to the metal electrode, the assembly method provided in this application uses the two planar constraint sections 12 of the heating element 10 to provide clamping force to clamp the two electrode components 30 and the insulating fastener 20. Since the welding step is eliminated, solder precipitation in a high-temperature environment can be avoided.

[0036] For example, in some embodiments, such as Figures 1 to 6 As shown, the two planar constraint segments 12 are parallel to each other, so that the clamping force applied by the two planar constraint segments 12 at various positions of the two fixed segments 31 is more uniform; correspondingly, the two fixed segments 31 are parallel to each other and both fixed segments 31 are flat, so that the plate surface of the two fixed segments 31 can be in close contact with the surface of the two planar constraint segments 12. Alternatively, in some embodiments, the distance between the two planar constraint segments 12 gradually increases from the center of the arc-shaped constraint segment 11 outward (i.e., from the inside to the outside), so as to facilitate the entry of the two electrode components 30 between the two planar constraint segments 12; or, in some embodiments, the distance between the two planar constraint segments 12 first decreases and then increases from the center of the arc-shaped constraint segment 11 outward (i.e., from the inside to the outside), which can facilitate the entry of the two electrode components 30 between the two planar constraint segments 12, and can provide a stable and reliable clamping force through the area with a small distance between the two planar constraint segments 12, so as to ensure that the two electrode components 30 are clamped and avoid disengagement.

[0037] For example, in some embodiments, such as Figures 1 to 6 As shown, the distance between the two planar constraint segments 12 is equal to the sum of the thicknesses of the insulating fastener 20 and the two fixing segments 31, so that the integral formed by the insulating fastener 20 and the two fixing segments 31 can smoothly enter and be clamped between the two planar constraint segments 12. Alternatively, in some embodiments, considering that the two planar constraint segments 12 have a certain deformation capacity, the distance between the two planar constraint segments 12 can be slightly smaller than the sum of the thicknesses of the insulating fastener 20 and the two fixing segments 31. In this way, an external force can be applied to the two planar constraint segments 12 to open them up, so that the integral formed by the insulating fastener 20 and the two fixing segments 31 can smoothly enter and be clamped between the two planar constraint segments 12. Then, the external force applied to the two planar constraint segments 12 is removed, and the two planar constraint segments 12 tend to return to their natural state to provide a stable and reliable clamping force for the insulating fastener 20 and the two fixing segments 31.

[0038] Considering the relatively long length of the lead segment 32 of the electrode 30, to avoid short circuits between the two electrode 30s, as one possible implementation method is... Figures 1 to 6 As shown, the atomizing core module 100 also includes two insulating protective sleeves 40, which are fitted onto the two pin segments 32 in a corresponding manner. It should be understood that the length of the insulating protective sleeve 40 is less than the length of the pin segment 32, so that part of the pin segment 32 is exposed for wiring.

[0039] In one possible implementation, the insulating fastener 20 is provided with a first mating portion 21, and the fixing section 31 is provided with a second mating portion 311. The first mating portion 21 and the second mating portion 311 cooperate with each other to fix the insulating fastener 20 to the electrode member 30. For example, such as... Figures 1 to 3 As shown, in some embodiments, the first mating part 21 is a protrusion, and the second mating part 311 is a groove or through hole adapted to the protrusion; or, in other embodiments, the first mating part 21 is a groove, and the second mating part 311 is a protrusion adapted to the groove, so that the insulating fastener 20 and the electrode 30 are fixed and positioned. It should be noted that the first mating part 21 cannot penetrate the insulating fastener 20 along the line connecting the two fixing segments 31, or in other words, the first mating part 21 cannot be a through hole, so as to avoid the two fixing segments 31 contacting each other through the first mating part 21, causing a short circuit between the two electrode 30s.

[0040] As one possible implementation method, such as Figures 2 to 6As shown, the atomizing core module 100 also includes a liquid guiding component 50. The liquid guiding component 50 includes an arc-shaped covering section 51 and two planar covering sections 52 extending outward from both sides of the arc-shaped covering section 51. The arc-shaped covering section 51 is attached to the outer wall of the arc-shaped constraint section 11, and the two planar covering sections 52 are attached to the outer walls of the two planar constraint sections 12 in a one-to-one correspondence. In other words, the shape and structure of the liquid guiding component 50 are adapted to the shape and structure of the heating element 10 so that the liquid guiding component 50 is fitted to the outside of the heating element 10 (i.e., the side away from the center), thereby forming an atomizing assembly with the heating element 10, the insulating fixing member 20, the two electrode members 30 and the liquid guiding component 50, so that the atomizing matrix is ​​adsorbed through the liquid guiding component 50 and the adsorbed atomizing matrix is ​​heated by the heating element 10.

[0041] As one possible implementation method, such as Figures 3 to 6 As shown, the atomizing core module 100 also includes a cylindrical mounting bracket 60, which supports and protects the atomizing component and allows the atomizing core module 100 to be installed inside the electronic atomizer 300. The mounting bracket 60 has a notch 61 on its peripheral wall. The atomizing component is axially inserted into the mounting bracket 60, and the planar covering section 52 passes through the notch 61 and protrudes outside the mounting bracket 60. This allows the side walls on both sides of the notch 61 to clamp the atomizing component. The lead section 32 passes through the opening of the cylindrical structure and protrudes outside the mounting bracket 60, facilitating connection between the lead section 32 and a power source (e.g., a battery) to ensure the heating element 10 operates normally. For example, the mounting bracket 60 can be made of metal or plastic. Using metal increases its strength, while using plastic reduces its weight. Those skilled in the art should be able to make a reasonable choice based on the specific circumstances.

[0042] As one possible implementation method, such as Figures 3 to 6 As shown, the mounting bracket 60 is provided with a number of liquid inlet holes 62 arranged circumferentially, so that the atomizing matrix can fully contact the liquid guide 50 through the liquid inlet holes 62 and be fully adsorbed by the liquid guide 50.

[0043] In the prior art, heating elements using metal materials have problems such as short lifespan and carbon buildup. As an alternative implementation, the heating element 10 is made of carbon fiber, which can not only heat the atomizing matrix normally, but also increase the number of repeated heating cycles due to the higher temperature resistance of carbon fiber, while avoiding oxidation. Therefore, the service life and performance of the heating element 10 can be improved.

[0044] Please refer to the reference again. Figure 7In a second aspect, this application provides an electronic atomizer 300, which includes a power module 200 and the aforementioned atomizing core module 100. The output terminal of the power module 200 is electrically connected to the pin segments 32 of two electrode members 30. For example, in some embodiments, the output terminal of the power module 200 is directly connected to the two pin segments 32; or, in other embodiments, the output terminal of the power module 200 is indirectly connected to the two pin segments 32 via a flexible connecting wire. Furthermore, the electronic atomizer 300 should also have a liquid storage chamber to store the atomizing matrix, thereby facilitating the heating and atomization of the atomizing matrix by the atomizing core module 100. Since the structure and beneficial effects of the atomizing core module 100 have been described in detail in the foregoing embodiments, they will not be repeated here.

[0045] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0046] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
